Manchester United’s equaliser should have been disallowed for offside.
Ander Herrera’s head was in an offside position when Marcos Rojo struck the free-kick.
When the shot was saved, Herrera ran on to the loose ball and pulled it back for Anthony Martial to score.
With the benefit of VAR, this goal would not have stood but it is still disappointing that Scott Ledger, the assistant referee, got it wrong.
He is one of the best assistants in England but this was a static situation and there were no defenders blocking his view.
